CROSS-REFERENCE TO RELATED APPLICATION

This Application claims priority to and benefit under 35 U.S.0 § 119(e) of U.S. Provisional Patent Application Ser. No. 62/132,311, filed Mar. 12, 2015 which is hereby incorporated by reference in its entirety as if fully set forth below.

FIELD

The present disclosure generally relates to the security systems for unmanned air vehicles such as recreational drones.

BACKGROUND

Security systems known are subject to cumbersome installation of constituent parts and associated static location of imagine devices (e.g. cameras) that are installed therein. Because the cameras are static and difficult to install, dark spots can be exploited by intruders. Additionally, it has been proposed to send recorded and/or streaming images to computing devices or portable computing devices such that the user of a smartphone can view information such as recorded images (or images being recorded) or messages. In this respect, portable computing devices such as smart phones or tablets have been used for storing, analyzing, and transmitting such information.

However, in order for any settings in a particular system to be manipulated (i.e. to view different cameras, move the location of a camera, or any other administrative function), an end user typically has to be near the location of the camera and/or be situated where the actual surveillance systems are located in order to make such changes permissible. It is with respect to these and other considerations that the various embodiments described below are presented.

Front-End System

FIG. 2 depicts an illustration of the automated drone security system architecture according to an example embodiment. According to certain embodiments, security system 200 may comprise a user-facing front-end 210 including software, firmware, and/or hardware for monitoring and/or controlling a drone 220. In some embodiments, this interface to the user may comprise a mobile application (“app”) 215 a or other software executable on a mobile computing device 210 (e.g. a smart phone). In another embodiment, the interface may comprise a web-based application 215 b accessible through a browser or other software, or a desktop application.

In some embodiments, the mobile app 215 a may include a client for managing one or more locations being secured by drone(s) 220 of system 200. A location may be configured with one or more of the following parameters: geo-fence (e.g., a two- or three-dimensional structure defining borders of the location); buildings (e.g., polygons with specified height); obstacles (e.g., polygons with assumed infinite height, effectively no-fly zones, etc.); markers (e.g., map markers identifying points of interest); and/or bases/docks 225 (e.g. map markers identifying locations of drone docks 225).

System 200 may also include several drones 220, wherein each drone 220 may be assigned to a specific dock 225, or to multiple docks for dynamic operations. In some embodiments, additional capabilities of app 215 a/215 b or other software may be available dependent on the drone 220 to be controlled or the characteristics of dock 225, device 210, and/or the associated server assembly. In an example embodiment, the app 215 a/215 b may determine the capabilities of a host device executing the software and configure itself accordingly. In another embodiment, the app 215 a/215 b may configure itself based on a configuration of the drone 220 to be controlled. Alternatively, the software of may come preconfigured for a particular host device, a host or target drone that can be defined by the end-user, or for a particular target drone.

In some embodiments, the app 215 a/215 b may provide or support functionality permitting drone 220 and location management. Moreover, the app may provide routine operation setting and scheduling with manual takeover of drones 220, role management, alerts during manual and automated control; and/or comment and sharing functionalities.

According to certain embodiments, the app 215 a/215 b may present information about associated drones 220 in a dashboard view. In an example embodiment, the operational status and/or battery charge of a drone 220 may be displayed and/or other displayable information may include drone destination, position, speed, heading, and altitude. Selecting a drone user interface item may bring up a view with editable details and controls to manage status of the drone 220 and assign it to a dock 225 or to execute one or more predetermined operations.

In some embodiments, the app 215 a/215 b may present information about currently running operations in the dashboard view. In an example embodiment, the operations may be grouped by location and/or one or more indication of each operation item may include a periodically updated image from the live video feed associated with the operation. A user may access an operation broadcast view by transmitting input through the user interface of the app 215 a/215 b (e.g. tapping or clicking-on or otherwise selecting an operation item).

In some embodiments, the user may receive notifications (e.g. alert messages) indicating the status of one or more current operations. For example, when a new operation starts, the user may receive a notification through app 215 a/215 b. Forms of notification include app notification within the app itself, email, and messaging (e.g., SMS, MMS, etc.). In some embodiments, multiple users may communicate with each other through a messaging interface of the app 215 a/215 b and/or other software. Through or outside of the messaging interface, users may be granted permission to view one or more live video feeds and operational statistics associated with the drones owned or operated by other users. In an example embodiment, a first user may provide a link to a video feed of drone operation underway to second user, The second user may follow the link to launch a live-broadcast interface showing a live view from the associated drone. Operations may be launched from the dashboard of app 215 a/215 b or the like.

In some embodiments, a suitable drone 220 may be selected for an operation automatically based on one or more operation parameters and status of available drones. A drone may also be selected based on factors such as proximity to one or more predetermined locations, battery status, size of a particular drone for a particular operation, range of the drone, speed of the drone, payload capability of the drone, or other factors.

According to certain embodiments, the interface of the app 215 a/215 b may also provide a calendar or other scheduling interface for managing one or more operations. For example, FIG. 11A describes an embodiment of app 215 a on device 210 depicting an exemplary event scheduler 250 a whereas FIG. 11B similarly depicts app 215 b and an exemplary event scheduler 250 b. Either event scheduler may schedule operations and may also be configured to repeat one or more operations on specified intervals during a time period (e.g., every hour from 8 am to 4 pm), on specific days (e.g., every Monday-Friday), or periodically (e.g. once every 4 weeks, every 2 months, etc.). One or more flight paths associated with a particular operation may be configured in advance by placing a plurality of waypoints on one or more maps. Components of the system 200, including app 215 a/215 b, may ensure that the flight path does not exceed a certain maximum duration, range, or other performance parameter, for example, a “safe” drone flight time. Users may also be able to view a list of recordings arranged by time and date. In some embodiments, the scheduling interface may include search functionality to improve ease of use as well as facilitating repeatability of one or more previously executed operations.

According to certain embodiments, the app 215 a or 215 b may include a playback interface for viewing captured video and other recorded data. For example, FIG. 12A describes an embodiment of app 215 a on device 210 depicting an exemplary event viewer 240 a whereas FIG. 12B similarly depicts app 215 b and an exemplary event viewer 240 b. This is particularly useful where a particular structure or object can be monitored to mitigate damage or losses associated with accidents as seen in FIG. 12B where a structure is on fire. In this instance, users may be able to immediately respond or the system 200 may be configured to automatically detect episodes as in FIG. 12B and coordinate with appropriate response personnel. The playback interface of each viewer 240 a and 240 b may be similar to a live-broadcast interface, however, the user may be able to control the playback position in the former.

Users may also be capable of appending a description, a title, or other notes to the recordings. Users may also be able to utilize viewers 240 a and 240 b in combination with one or more maps and such appended information may be viewable as part of the list of recordings. In another embodiment, the app may launch or trigger another application on the host device for viewing content. A user may also share recordings with other users through the app 215 a and 215 b. In some embodiments, a user may be able to tag and share only desired portions of recordings such as clips of interest.

Additionally, in regards to live viewing, as seen in FIGS. 7-10 which depict exemplary live or previous event viewers 240 a, app 215 a on device 210 that may include different controls and indicators for system 200 and corresponding end-users. For example, in FIG. 7, viewer 240 a is shown displaying information related to an event entitled, “Lake Lagunita”, wherein one or more alerts have been defined with information related to an “alert event” that earlier took place at a predetermined location, “West Building Entrance”. Information may be compiled associated with the event of FIG. 7 including a combination of videos, photos, location, and the like. Similarly, FIG. 8 depicts information related to the vent of FIG. 7 as seen in app 215 a of device 210 with information related to a plurality of locations associated with the location of FIG. 7, including nest 225, one or more markers associated with the location, building, a perimeter of the location, and the ability for system 200 to dispatch one or more drones 220 to execute a path, go to a location, or carry out one or more operations.

Similarly, FIG. 9 depicts a view one or more maps in app 215 a that show live video feeds as well as path of one or more drones 220 of system 200. In this respect, a user may select which drone 220 to operate, which operation to execute as well as access information related to operational status, position, path, battery, or the like. Similarly, as seen in FIG. 10, app 215 a may be capable of imparting image and/or video control to end-users. For example, through the app 215 a a user may manually or the system 200 may automatically control camera tilt, heading and/or pinch for cameras of drone 220 between a plurality of orientations and positions.

Back-End Architecture

According to certain embodiments, the drone security system 200 may comprise a back-end including one or more servers 240. A server 240 may perform various functions including collision mapping, drone coordination and air traffic control as well as storage/processing of captured images and video streams. In one example embodiment, the back-end architecture may comprise, or be in communication with, one or more of a database server, web server, drone coordination relay, stream server, notify server, and/or a scheduler. In some embodiments, this functionality may be split between multiple servers, which may be provided by one or more discrete providers. In an example embodiment, a web service for hosting computer applications or other cloud computing resource may be dynamically provisioned to match demand and ensure quality of service of the drone security system 200. For example, the drone security system 200 may be compatible with the Amazon EC2 cloud computing platform.

Database Server

According to certain embodiments, the above-described database server may store master data, telemetry information, and mission data as well as logging and trace information. Software of the database server may be based on the object-relational database system PostgresSQL the database server is not so limited other approaches may be used as needed or required. This database system is not limited to only organizing and storing data and instead, it may be also used to eliminate a need of having an application server (e.g. 2nd Layer). In some embodiments, almost every functional requirement may be realized by using the database's programming language, PL/pgSQL. The database may also provide an API to the web server for data interchange based on JSON specifications. In some embodiments, the database may also directly interact with the described drone coordination relay to control and track one or more drones 220.

According to certain embodiments, the database server may be optimally designed for storing large amounts of data, responding quickly to incoming requests, having a high availability and historizing master data. In an example embodiment, the database server may store ten megabytes of raw data (e.g. data related to telemetry and tracking), as well as 200 megabytes of video material (e.g. per drone 220). To handle this amount of data, a sophisticated combination of table partitioning, table inheritance as well as database clustering may be implemented to fulfill these requirements.

Mission Control Module

According to certain embodiments, the mission control module may be part of the database backend. FIG. 4 depicts an illustration of drone state transitions during an exemplary mission, according to an example embodiment. The states marked with triangles, including drone states and user command states, are handled by the Mission Control Module. In some embodiments, the mission control module may perform one or more of triggering one or more scheduled missions, dispatching a drone 220 on a mission, ordering control of operations, status tracking of a drone 220 during missions, accepting and delivering operator instructions, finalizing and archiving missions and mission data, as well as ensuring operation safety as the drone 220, other drones 220, and other static and dynamic objects.

This module may directly interact with the drone coordination relay and/or drone navigator process and may also control these components based on mission-specific requirements, sensor data, drone states, state transitions, or the like. The mission control module may also handle states like low battery, failover in case of unresponsive backend hardware and malfunctions indicated by the drone 220 itself. In some embodiments, this module may include logic for collision avoidance.

Web Server

In an example embodiment, the web server may be a standard component based on Apache Web Server and PHP or the like. For availability and performance reasons the load may be balanced across multiple nodes.

Drone Coordination Relay

According to certain embodiments, the drone coordination relay may directly interact with the database server. For example, if a mission is scheduled, manually or automatically, the database server may cause the drone coordination relay to dispatch a mission at drone coordination and fork a drone navigator process. This process may run independently from the drone coordination relay and/or take over the following tasks, including, reading the status from the drone periodically (e.g., every two seconds) and write the status to the database backend. The periodic reading may be customizable so that reading is done more quickly or more slowly depending on bandwidth, storage capabilities, or user preference. The database may also return with the next instruction to proceed (e.g., a next waypoint to approach).

When an instruction is given by the database backend, the drone navigator process may contact the drone coordination to initiate the desired action. This action may be, for example, to fly to a new destination, to fly a pattern at the current position, or to tilt the camera. If the database backend indicates that the last waypoint has been reached, then the drone navigator process may initiate a return-to-landing procedure. After the drone has landed and switched back to an “idle” state, the process may finish. When a mission starts again the drone coordination relay may fork a drone navigator process and/or also a streaming server process. In some embodiments, the drone coordination relay may be programmed using Shell Scripting Language.

Stream Server

According to certain embodiments, the Streaming Server Process may receive the video from one or more cameras of the drone and multiplex it to connected consumers. Additionally, the Streaming Server Process may take periodic snapshots of the video and store the video on disk. If a mission has ended, the Streaming Server Process may archive the video and register the file in the database. Afterwards the Streaming Server Process may end.

Notify Server

According to certain embodiments, the Notify Server may send notifications to the user including instant messages within the app, SMS messages, and/or emails to user devices like mobile phones, tablets, laptops, personal computers and other computing devices. If a predetermined condition is recognized at the database backend (e.g. a predetermined level in a battery of the drone or sensory level from an onboard infrared sensor indicating a change in environment of a location be surveilled), an instant message may be triggered and delivered by the Notify Server.

Scheduler

According to certain embodiments, the Scheduler may automatically start and reschedule repetitive missions. The scheduler may also observe the status of drones currently not airborne and execute the pending backlog of the Drone Coordination Relay. Moreover, the scheduler may initiate daily maintenance operations on the database and the operating system. In some embodiments, daily maintenance on the database may include one or more the following tasks: 1. Reorganizing tables; 2. Computing table statistics for better performance; 3. Truncating outdated protocol data; 4. Creating new partitions; and/or 5. Backing-up of the database.

Drone Architecture

According to certain embodiments, the drone security system 200 may include, or be configured to operate with, one or more drones 220. In some embodiments, the drone security system 200 may be compatible with multiple drones 220 of various makes, models, and capabilities.

An exemplary drone 220 useable with the drone security system 200 may meet one or more of the following criteria: 1. Flight time/range: a fully charged drone 220 may be able to fly for 10-30 minutes depending on drone type; 2. Loiter time: drone loiter time at each waypoint may be independently configurable; 3. Camera focus, tilt, and zoom control: camera may be controlled via app; 4. Safety systems: deployable parachute, radio-based self-position broadcast, emergency landing system, and e-stop functionality; and/or 5. System redundancy: drivetrain hardware, communication hardware, onboard computation hardware, and onboard sensors (e.g. IMU, GPS) may have backups or be able to perform in a reduced capacity.

In some embodiments, a drone 220 may also support wireless, mobile, and/or satellite network connections. For example, a drone 220 may communicate telemetry and video data via LTE connection. Encryption or other technology may also be used to secure communications to and from drone 220.

In some embodiments, the drone 220 may include one or more multiple sensor devices such as a camera or other image capture device, an infrared sensor, Optical, multi-spectral, hyperspectral, laser, and optical SAR technologies, gas sensors, or the like mounted thereon. In those embodiments where drone 220 is equipped with a camera, the camera may be permanently affixed or removably attached. The camera may capture images and/or video of the drone 220's surroundings. In some embodiments, the captured video or images may be streamed live from the drone 220 through the backend to the app. In another embodiment, the content may be streamed from the drone 220 to the Copilot or device hosting the app software, or to the Copilot and then to the app over another network or connection. In another embodiment, the drone 220 may save video locally to an on-board memory or other storage and/or remotely save captured content to an external storage medium. The captured content may later be retrieved from the drone 220, the external storage medium, or the like, for example, after landing in a nest, or other docking station.

In some embodiments, the drone 220 may be able to automatically change the resolution, frame rate, or other quality of video or images being captured. For example, a drone 220 may typically capture video at a first resolution for streaming or local recording. When an area of interest appears or a particular event or condition is satisfied, the drone 220 may switch to capturing video at a higher resolution. This change in quality may be triggered manually by the user, or occur automatically in response to an event. For example, higher quality capture may be activated responsive to detection of activity by one or more sensors such as a sudden change in temperature or ambient noise level that can cause a drone 220 to change a quality of capture.

In some embodiments, the drone 220 may be equipped with a variety of additional sensors, including but not limited to, accelerometers, gyroscopes, altimeters, barometers, microphones, temperature sensors, thermal optics, and location sensors. Data provided by some or all sensors of drone 220 may be transmitted back to a front-end or back-end computing device for presentation to a user and/or processing/storage. According to certain embodiments, a drone 220 may operate according to one or more of the following states: in storage (e.g. drone 220 has not been assigned to a base, non-operational); charging (e.g. drone 220 is assigned to a base and is docked and charging); on duty (e.g. a drone 220 is currently flying a mission); malfunction (drone 220 has malfunctioned and needs to be repaired); and in repair (drone 220 has been unassigned from its base and is being serviced).

According to certain embodiments, a drone 220 may also engage in one or more of the following operations: manual (e.g. a user manually dispatches a drone 220 to a specified coordinate using the app); alarm (a drone 220 is automatically dispatched to where an alarm was triggered); and scheduled (e.g. routine drone 220 flights are dispatched automatically in predefined intervals).

In some embodiments, a user may launch a manual operation as well as assume manual control of ongoing alarm and scheduled operations. During manual operation, only a single user may have manual control of an operation. In an example embodiment, only the current operator may dismiss, end, edit, and/or suspend a manually controlled operation. In some embodiments, an operator may prompt another user to assume manual control or assign manual control to another user. In another embodiment, a user with sufficient privileges may override a current operator and assume manual control themselves without permission.

During manual operation, a user may send a drone 220 to a plurality of coordinates by interacting with the map, as well as controlling the camera pan, tilt, and zoom using gestures, a mouse, or other input device. After dismissal or completion of an operation, the drone 220 may autonomously return to its dock or base or another predetermined position, In some embodiments, an operation may be automatically dismissed if one or more predetermined conditions are satisfied such as the battery charge of a drone 220 being low, or the drone 220 is otherwise forced to retire. An operation may also be assumed by second drone 220 when a first drone 220 is forced to retire. This relay may be performed with minimal or no interruption to drone broadcast.

In some embodiments, drone takeoff and/or landing may be handled autonomously by the drone coordination server. Alternatively, a drone 220 may be at least partially under manual control during these sequences.

Copilot And Autopilot

According to certain embodiments, the drone security system 200 may comprise a “Copilot” for assisting with drone management. The Copilot may include software, firmware, and/or hardware external from a drone 220 and configured to receive telemetry data from the drone 220, In an example embodiment, the copilot may comprise proprietary communication and drone management software at least partially running or resident on a computing device. For example, the copilot may run on a Raspberry Pi or other system on a chip (SOC). Alternatively, the Copilot may comprise a combination of different single-board computers.

In some embodiments, the Copilot may receive user commands from the app or other user software. The Copilot may be linked to the Drone Coordination Relay by ROS and/or HTTP/REST. The Copilot may communicate with an Autopilot system for remotely piloting an aircraft that is out of sight. In an example embodiment, the Autopilot system may comprise an open-source autopilot system oriented toward autonomous aircraft.

Access Control

According to certain embodiments, the system 200 may include access control functionality, wherein access to drone functionality may be limited on a per-user(s) and/or per-location(s) basis. Permissions may define which functionality is available to a user. A role may be a system-wide group or class of permissions and a user may be granted a different role for each location.

Drone Dock

According to certain embodiments, the drone security system 200 may comprise a docking station or other platform 225 for storing and landing/launching drones 220. For example, FIG. 5 depicts an illustration of the automated drone security system dock in a closed state, according to an example embodiment. FIG. 6 depicts an illustration of the automated drone security system dock in an open state, according to an example embodiment.

Such a dock 225 may be referred to herein as a “nest.” In some embodiments, the dock 225 may serve as a housing for the drone 220, and may be located on rooftops, cars, in a backyard, or elsewhere. The dock 225 may protect the drone 220 from the elements while it recharges or awaits an operation. Once a dock 225 is installed, the drone 220 fleet may be operated remotely, so that there is no need to manually access the dock 225 during routine operation.

In some embodiments, a drone 220 may charge while docked. In an example embodiment, a nest may supply a minimum of 12 volts at 10 amps for fast charging. The dock 225 may be connected to an external power grid, or receive power from alternative sources such as solar, wind, and/or thermal and/or store this power in an external power supply such as one or more batteries. In certain embodiments, the external power supply of the dock 225 may be one or more backup batteries so that the dock 225 may still open/close or even continue to charge drones 220 during a power outage, overcast weather, and/or other disruptions to the power supply.

In some embodiments, a drone 220 may be charged through induction or through contact with conductive receivers on the dock 225 and the body of the drone 220. In an example embodiment, the conductive receivers may be conductive pads on the legs and/or feet of a drone 220 that contact charging terminals on a floor or landing pad of the dock 225. In some embodiments, a drone 220 may be “hot charged” such that drone 220 down time or unavailability in between or during operations may be minimized.

In some embodiments, the dock 225 may maintain a network connection through a wired (Ethernet) or wireless connection (e.g., WiFi, 3G, 4G, LTE, etc.). The dock 225 may also report dock status, including whether the dock 225 is open or closed, empty or occupied, charging a drone 220 or not, receiving external power, the location of the dock 225, a level of charge of one or more backup batteries, maintenance alerts, or other sensor data related to the dock 225. In another embodiment, the dock 225 may also share its network connection with a docked drone 220, or assume responsibility for reporting drone status in addition to or in place of the drone 220.

In some embodiments, the dock 225 may be equipped with one or more cameras. Accordingly, the dock 225 may also provide a live video feed or two-dimensional and/or three-dimensional images of its surroundings. The dock 225 may also be equipped with various sensors and in yet another embodiment, the dock 225 may be equipped with radar or other object-detection systems.

In some embodiments, the dock 225 may provide autonomous landing guidance. For example, differential GPS data detected onboard (e.g., RTK GPS) may be used to automatically or partially automatically guide a drone within range of optical recognition. Once the drone 220 is in range, cameras or other image capture devices may be used to recognize lights or other identifiers on the drone 220. In an example embodiment, there may be multiple mono and/or stereo cameras on the landing pad of the dock 225. The drone 220 may be outfitted with focused LED lights in custom patterns and lighting up in sequence. Redundant visual sensor placements and LED arrays/reflectors on the drone 220 may be tuned in such a way that an LED array/reflector is always visible to one of the optical sensors on dock 225, even if the lighting conditions are less than ideal if, for example, the sun lies directly in the line of sight of one or more of the visual sensors.

Additionally polarized filters may be employed, so that the camera recognizes the LED arrays/reflectors even with conflicting sources of light. A strobing pattern or other predetermined pattern may help the processor of the dock 225 identify the orientation and approximate distance of the drone 220. Accordingly, the dock 225 may visually verify that the correct drone 220 is in appropriate position to dock 225. An imaging algorithm may be used in conjunction with telemetry to establish a landing trajectory, which may then be communicated to the drone 220.

In some embodiments, the dock 225 may be secured to prevent physical and/or electronic tampering. For example, a locking mechanism may keep the dock 225 sealed when a drone 220 is not preparing to launch or land in the dock 225. Moreover, electronic access to the dock 225 may be limited through access control as described herein or the like. In an example embodiment, intrusion or tampering may be detected automatically so that a response can be triggered (e.g. setting of an alarm). The alarm may include emitting an audible siren or other indication of emergency. The alarm may also include notifying an owner or operator of the dock 225 by the app, textual message, or other electronic means. In some embodiments, dock 225 s expected to be placed in high-risk areas may be hardened or contain additional features to prevent intrusion or weather damage.
